Patent CA-2389069-A1 (CA)
Inventor: SCHULZ FRITZ
IPC: B65H29/50
Filed: 2002-06-05
Abstract: A stream of successive sheets of paper, foil or the like is converted into a series of piles at a stack-ing station where successive sheets are caused to descend onto a pallet which is adjacent a monitoring device serv-ing to transmit signals denoting the levels of successive uppermost sheets of a growing pile. Such signals are processed by a unit which controls one or more valves in a pneumatic elevator for the discharge end of the endless flexible conveyor which supplies successive sheets to the stacking station. The elevator ensures that the distance between the discharge end of the conveyor and the uppermost sheets of the growing pile remains within a preselected range. This contributes to the accuracy of stacking of sheets on their pallet.

Title: Droplet polymerization method for synthesis of molecularly imprinted polymers
Inventor: NORTON TUCKER
IPC: C08F2/00
Filed: 2002-06-07
Abstract: A droplet polymerization process is provided to create efficacious molecularly imprinted polymers (MIPs). Such imprinted polymers have increased surface area for adsorptive or catalytic reactions. This method provides for monomer-template interactions in the absence of a suspending medium, thereby permitting formation of MIPs with increased template molecule selectivity and substantial processing advantages. The process is particularly useful for separating isoflavones from soy whey.

Title: Method for controlling the temperature of preforms and a temperature-controlling device
Inventor: PESAVENTO MODESTO
IPC: B29C49/78
Filed: 2001-03-03
Abstract: The invention relates to a method for controlling the temperature of preforms consisting of a thermoplastic material. The preforms are to be blow-moulded into containers. The preforms are subjected to a range of temperatures along their periphery and are guided along a translation path, past at least one heating device (14), during the temperature-controlled process. In addition, the preforms are at least occasionally rotated about their longitudinal axes.  The control of said rotational movement (8) is, at least at times, carried out independently of the translation movement. The translation movement is controlled in such a way that the peripheral areas of the preforms which are to be subjected to a higher temperature face the heating device for longer periods than the peripheral areas of the preforms which are to be subjected to a lower temperature. Said control has a desired value generator for a temporal modification of the path of the desired value of the rotational speed of the preforms.

Title: Method of converting a series of m-bit information words into a modulated signal
Inventor: SCHOUHAMER IMMINK KORNELIS ANT
IPC: H03M5/14
Filed: 2001-02-02
Abstract: This invention relates to a digital modulation method and apparatus used for recording an audio or video signal, computer data, and etc on a recording medium such as an optical or magneto-optical disc. Data words of m bits are translated into code words of n bits in accordance with a conversion table.  The code words satisfy a (d, k) constraint in which at least d "0"s and not more than k "0"s occur between consecutive "1"s. The n-bit code words alternate with p-bit merging words which are selected such that between the leading "1" in the code word following the merging word and the trailing "1"  in the merging word are at least d "0"s, and further that between the trailing "1" in the code word preceding the merging word and the leading "1" in the merging word are at least d "0"s. The merging word that satisfies said conditions, yielding the lowest dc imbalance of the modulated signal obtained after modulo-2 integration of the catenation of the alternate code words and merging words is selected. Then, the modulated signal is generated by the catenation of alternate code words and merging words integrated modulo-2 in which a "1" becomes a transition and a "0" becomes an absence of a transition.  A unique synchronizing word is inserted periodically.

Patent CA-2406619-A1 (CA)
Inventor: SUNTER STEPHEN K
IPC: G01R31/3185
Filed: 2001-04-03
Abstract: A method and built-in circuit are described for testing direct current (DC) parameters of the input and output pins of a circuit by testing the transiti on time interval for rising and falling voltage transitions. When the voltage transition is for an integrated circuit (IC) pin having a known capacitance,  which can include off-chip capacitance, the magnitude and direction of curre nt at the pin can be determined. The method enables testing an IC via a test access port (TAP) comprising a subset of the pins of the IC, for example in conformance with the IEEE 1149.1 boundary scan test standard. For sufficient ly small current magnitudes, such as leakage current (IIL and IIH), the techniq ue can use only on-chip circuitry to sample a pin voltage at time intervals aft er an output transition is generated at the pin, the time intervals pre- determined to be less than the transition time interval. For larger current magnitudes, such as IOL and IOH, an off-chip capacitance of known value is connected to the pin to decrease the rate of transition. For greater accurac y, an off-chip resistor of known value is connected to the pin, and the transition time interval due to the driver is compared to the transition tim e interval due to the resistor.

Patent CA-2409891-A1 (CA)
Title: Electromagnetic wave assisted chemical processing
Inventor: HOLL RICHARD
IPC: B01J19/10
Filed: 2001-05-10
Abstract: A window allows the introduction of radiation energy into an annular processing chamber (44) filled with a material to be processed. The chamber is formed from coaxial cylinder members (30,32) rapidly rotating relative to one another. The chamber (44) can be thin enough so that it is short compared to the penetration depth of the radiation through the material, providing even exposure of the material to the radiation. Also, eddies created in the material by the relative rotation enhances the even exposure. When the material inside the annular processing chamber (44) is opaque, resulting in an insignificant penetration depth, the eddies still insure that the material is evenly exposed to the irradiation.
